**June 8th, I tweeted this:**
*"Yesterday, I witnessed an **incredible talk that has instantly secured a place in my top three all-time tech talk list.** It was delivered by [@JulienTopcu](https://twitter.com/JulienTopcu) and [@JosianChevalier](https://twitter.com/JosianChevalier) at [#DDDEU](https://twitter.com/hashtag/DDDEU?src=hashtag_click) in Amsterdam. Their presentation was nearly flawless, excelling in both content and delivery."*

This is the talk #DDDFR and Payfit would like to offer you for this exceptionnal live event with 2 incredible mandalorians.

**Abstract**
Just as models should be iterative, strategic design should change when the context and our understanding of the problem evolve. As a model grows to solve more problems, it becomes less supple in its ability to evolve. Tensions arise within the model that struggles to stay coherent.
Eventually it reaches a critical mass and becomes a big ball of mud.
How do we know when it’s time to let new models emerge? How do we carry on the decision to split a model? How can we handle the progressive differentiation of our models while avoiding unnecessary coupling? It’s not as easy as a clean axe cut in the middle, finding the right boundaries is hard.

We would like to introduce the Model Mitosis, a dynamic pattern used to split a model into multiple ones that will get shaped and decoupled iteratively.
